Recommended 24v 300ah battery
@DownsDweller done exactly this comparison last spring when I was expanding my solar setup. Pylontech US5000 is rock solid but it's really designed around their ecosystem — works best paired with...

LF SGP 10kw off grid inverter
@Wendy1968 14 months is a decent run — any issues with the comms side? I've heard mixed things about the BMS integration on these.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@CallumHobbs depends massively on the freezer tbh. A decent efficient one (Dometic, Engel, etc.) might only pull 30-50Ah overnight in warm weather — well within your 200Ah.

Finding the perfect set up as a beginner
@CarolThomas79 honestly? figure out your actual daily consumption first — before even looking at panels or controllers. Most beginners skip straight to "I want 400W of solar" without...

Multi HS19 Solar 15k
Saw the announcement drop for the Victron Multi HS19 Solar 15k — genuinely curious what people here think about it landing in the UK market. From what I can tell it's aimed squarely at that...

Two MPPT showing on CCGX but not in VRM-portal
Had a similar head-scratcher with my setup a while back — both MPPTs showing perfectly on the CCGX screen but the VRM portal was only pulling data from one of them.

Swapped out my 100Ah AGM for a 100Ah LiFePO4 — same capacity but it feels like a completely different setup
PV_Fan | 312 posts | 🔋 Regular The usable capacity difference is the real kicker — your 100Ah AGM was probably giving you 50Ah usable max, whereas the LiFePO4 you can push to 80-90Ah no problem.

Anyone else had their BMS cut out in cold weather? Sharing my experience with a 200Ah LiFePO4
@EmmaPowell74 had this with my setup last February — panels were producing fine but the Fogstar just refused to take charge til gone 10am.

Charging an EV from a cabin solar setup — anyone actually doing it regularly?
Been toying with the idea of running a basic slow charge (3.7kW) for my van from the cabin array when I'm parked up.

Get prices in Node-red directly out the Cerbo GX
@MaxFrost it's definitely a Cerbo thing — Node-RED runs in a fairly locked-down container on there. If you want proper persistence you've got two options really: Enable file-based context storage...

EG4 Flex boss 18 Max PV input Voltage = 600VDC? Is that the total for the entire inverter or is that per Mppt line in? I am confused.
Pretty sure that 600V is the max input per MPPT, not the whole inverter combined. Most hybrid inverters work that way — each MPPT tracker has its own voltage ceiling. Worth double-checking the EG4...

Anyone else using cheap Chinese PWM controllers or is it a false economy?
@FormerMariner1 switched from a £15 no-name PWM to a Victron MPPT 75/15 on my van setup and the difference in harvest was immediately obvious — especially on cloudy days when MPPT really earns its...

Multi RS solar Grid limit ingnored
Seen a few people mention this lately and it's worth flagging here too — the grid feed limit on the Multi RS Solar seems to get ignored under certain conditions, and it's a bit of a headache. My...

Sprinter 12V/240V dual system walkthrough
Split-charge definitely makes sense if you've got the alternator output to spare. Running both 12V and 240V simultaneously without proper separation is asking for trouble – you'll hammer your...
